Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed July as, 1913. Serial No. 781,418.

T 0 all whom it may concern:

Be it known that I, ELMER E. HAUER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Motors, of which the following is a specification, reference being had therein to the accompanying drawings. r 1

My invention relates to motorsand more particularly to motors for driving boiler tube, cleaners that are adapted 'to travel through a tube with the cleaner although they may be used for other purposes.

The object of my invention is to providesimple, strong and eflicient motors that will withstand the hard usage incident to the particular service for which they are designed and so arranged that they can be easily assembled and readily taken apart.

With these and other ob ects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

In the accompanying drawings which form' a part of this specification Figure 1 is a longitudinal section on the line 1-1 of Fig. 3 showing one form ofmotor embodying my invention; Fig. 2 is a like section on the line 2-2 of Fig. 3; Fig. 3 is a cross-section on the line 33 of Fig. 1; Fig. l is a cross-section on the line -14; of Fig. 1; Figs. 5 and 6 are cross-sections on the'line 5-5 of Fig. 1, Fig. 5 showing ported plate at the limit of its throw in one direction and Fig. 6 the limit of its throw in the opposite direction; Fig. 7 is a longitudinal section of a modification; Fig. 8 is a cross-section on the line 88 of Fig. 7 and Fig. 9is a crosssection on the line 99 of Fig. '7.

Like numerals represent the same parts in the several views.

Now referring to the form of motor shown in Figs. 1 to 6 inclusive 1 represents a holding member which may be divided into any number of parts, but is shown as split preferably in the direction of its length at 2 into two parts and has a chamber 3 therein with oppositely disposed end walls 1? forming bearings in which removable bushings 4 are preferably employed, and said bushings are held against rotation bv dowel-pins 4*.

A motor cylinder 5 is seated within the chamber 3 and is secured against rotation by a dowel-pin 5 In the present instance I radially into the chambers 7 and 8 in a well 55 known manner. 1

The rotary motor member 6 is provided with a shaft 10 extending forwardly and rearwardly therefrom and preferably formed integrally therewith as shown. Said shaft is journaled in the bearings formed in or carried by the end portions 1 of the holding member. The forwardly extending portion of the shaft projects through the holding member and is screw-threaded at 11 to attach a tube cleaner or other tool to be driven. Wearing plates 12 are shown seated in recesses formed in the holding member on opposite sides of the rotary motor member and said plates are held against rotation by dowel-pins 12.

Inlet ports 13 extend through the rearwardly extending portion of the shaft 10 into the body of the rotary motor member and intersect cross-ports 14 which open into the working chambers in the rear of the ,piston blades.

A plate 15 seated in a recess at the rear end of the holding member and abutting the rear end of the shaft 10 is provided with ports 16 adapted to register with the ports 13 of the rotary motor member. Said plate is held against rotation by a dowel-pin 15*. Anotherplate 17 seated in a recess formed in the plate 15 is provided with ports 18 of greater width at one end than the other-as particularly shown in Figs. 5 and 6. In Fig. 5 the ports18 of the plate 17 are adjusted to the circular ports l6 ofjthe plate 15 to admit the greatest possible quantity of the motive agent, and in Fig. 6 the adjustment is for the minimum quantity'and of course the adjustment can be made at any point'between the maximum and minimum. When the adjustment has been made to suit the conditions of the service in which the motor is employed the plate 17 is tightened in place by a set-screw 19. The plate 17 is further provided with a peripheral recess 1.7 and a pin 15 fixed in the plate 15 and while said set-screw can be loosened to admit of the ported plate 17 being turned, the arrangement is such that the plate 17 is se cured to the plate 15 and cannot be lost therefrom. Furthermore the plates 15 and 17 have graduating marks 17 oppositely disposed on the respective plates so that the operator can readily adjust the admission of the motive agent to the quantity desired.

The respective ends 1*" of the holding member are tapered or inclined as shown at 1 and a casing 20 having as a part thereof a securing ring or plug 21 screw-threaded thereto is provided for said holding memher, said casing and ring having inclined inner walls to engage the inclined walls 1 of the holding member, the arrangement being such that by screwing the ring 21 to the casing tightens the holding member in its assembled position within the casing. The casing is provided at its rear end with a screw-threaded opening 22 for attaching a supply conduit and exhaust ports 23 lead from the working chambers through the front end of the holding member into an annular chamber 2 1 formed between said holding member and securing ring and thence through ports 25 in said securing ring. The recess 25 in the ring 21 is for the engagement of a spanner wrench.

This motor is assembled by first placing the wear plates and bushings on the shaft; then inserting the piston blades in the recesses of the rotary motor member; then inserting the parts so assembled in the motor cylinder; then placing all of said parts within the holding member; then placing the ported plates in position and inserting all into the casing through the front end and securing it therein by attaching the securing ring.

The motor shown in Figs. 7, 8 and 9 is similar to the one shown in Figs. 1 to 6 inclusive and heretofore described with this modification that the casing 20 is made in two parts having outer ends to engage the respective ends of the holding member 1 and screw-threaded at their inner ends at 26 to the holding member.

It will be seen that the holding member carries the bearings at the respective ends thereof and gives a very rigid construction to withstand the lateral strains which are very great in the particular service for which the motor is designed; and further these bearings being within the holding member can be bored in perfect alinement at one operation.

Various modifications in the details of construction may be made without departing from the principle of my invention and I do not wish to be understood as limiting myself to the precise details hereinbefore described and shown in the drawings.

My co-pending application Serial Number 27,199, filed May 10, 1915, which is a division hereof, covers constructions in which'a holding member separable by being split in the direction of its length is specifically claimed.

Having thus described my invention I claim i v 1. In a rotary motor, a motor cylinder, a split holding member having a chamber in which said cylinder is seated and means adapted to engage and secure said holding member in assembled position, substantially as described. I.
